Specification of Letters Patent.

Patented July 31, 1917.

Application filed January 24, 1917. Serial No. 144,183.

To all whom it may concern:

Be it known that I, THOMAS E. MURRAY, a citizen of the United States, residing-at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Valves, of which the following is a specification.

The invention'is a valve, and consists in the construction more particularly herein; after claimed, whereby the manufacture is cheapened and simplified.

In. the accompanying drawings.-

Figure 1 is a' vertical section of my valve. Fig. 2 is a transverse section of the valve seat on the line a; n of Fig. 1.

Similar letters ,of reference indicate like parts. 7 j

A is the valve casing, preferably made in. two longiti'ulinally divided partselectrically welded at their meeting edges. The laterally projecting tubular portion B of said casing is exteriorly threaded'to receive the (rap (,1, which has a tubular portion l) forming the stufiing-box forthe valve stem l and receiving the usual packing F, gland G and threiuled cover H. To the inner side of mp0 is electrically welded a plate J, which retains the packing in the boxD.

The valve stem 1*] is threaded to engage in a nut K. Said nut is received in and held in. place by a steel cup L. welded at its circumferential edge to plate J, and having in its bottom an opening for the valve stem.

At one end of the casing A. is a shoul- (lered circular enlargement M which re ccives the enlarged end of the inserted tube N which is closed at its. inner end by a. wall 0. Said tube is made of struck up, stamped or pressed sheet metal intwo lflllglldfllllllllly divided sections united at their meeting time wall R is edges by electric Welding. flat, as shown in Fig. 2, and has an opening which receives the internally beveled flanged ring 1. tween wall It and the flange of ring P. The valve S is seated in the ring P and secured on the end stem E. The stem carries the A. ring washer Q is inserted beusual hand wh'eel T, by turning which said stein, may be'rotated to open or close the valve.

I claim: I

1. A tubular casing having eno openings and a lateral tubular projection, a 'cap on said projection, avalve'stem pawing through said cap, a nut within said casing receiving a threaded portion of said valve stem, a metal cup having its edges carried by said cap, inclosing said nut and having an opening in. its bottom for the passage of said stem a valve on said stem, and a partition in said casing having a valve seat opening receiving said valve.

2. A tubular casing having end openings and a lateral tubular projeetion, a cap on said projection, a tubular shilling-box in said cap, a platoon the under side of said *cap closing said box, a valve stem passing through said Stlllllngd'mX and plate, a nut within said casing receiving a threaded por-' tion. oi? said stem, a metal cup having'its ialges'secured to said plate, inclosin'g and nut and having an opening lnj'its bottom for the passage of said stem, at valveon said stem, and. a partition in said casing having a valve seat opening receivingsald valve.

d. A casing having end openings, a tube entering said casing closed at its inner end, and at its outer end fittll'lg ln one of sandy .cnd openings, the said 'tube being formed.

in two sections longitudinally divided on a plane eccentric to the secured outer end of. said tube, one of said sections havinga valve seat in its wall, the said sections being stamped, pressed or struck up from heet metal and electrically welded at theiringintcring edges, a valve in said seat, and means for opening and closing said valve.

l'n testiinony whereof I'have allixed my signature in presence of two witnesses.
